filter position in config file.
by openbsd misc 26 Nov '09

26 Nov '09

I had a script generate some filters and add them to the very end of bird.conf (latest version 1.1.6) and if I do a birdc -> configure it complains no such filter. If move the filters above the bgp protocol section they are found ok. Are filters location specific in the config file ?

state of ipv6
by Martin Kraus 23 Nov '09

23 Nov '09

Hi. I'd like to ask what is the state of ipv6 in bird. I know it doesn't support OSPFv3 but last time I tried, ipv6 RIP didn't work either. Has something changed or do I have to use a different routing daemon for ipv6? thanks mk

Problem setting IPv6 next-hop in BGP
by S.H. Verbrugge 20 Nov '09

20 Nov '09

Hello, I'm new to this list, so please bear with me. I'm trying to set up a BGP route advertising server with BIRD, in order to update IPv6 static routes to a juniper router. My configuration is as follows (addresses omitted to avoid identification): ==START== log syslog { debug, trace, info, remote, warning, error, auth, fatal, bug }; log stderr all; router id <omitted>; debug protocols all; protocol device { scan time 10; # Scan interfaces every 10 seconds } protocol static { route <subnet>/64 via <gateway>; route <subnet>/64 via <gateway>; route <subnet>/64 via <gateway>; } protocol bgp { local as 64515; source address <own address>; rs client; export filter { if source = RTS_STATIC then { #bgp_next_hop = <gateway>; #gw = <gateway>; accept; } }; neighbor <omitted> as <omitted>; } ==END== I can see the correct routes being advertised, even with the correct 'via' in Debug traces, However, received routes are in the form of: <subnet>/64 via <bird source address>. I'm sure I haven't set next-hop self, so this behaviour seems strange to me. Could anyone please provide some insight into this?

config syntax checker
by Wolfgang Hennerbichler 19 Nov '09

19 Nov '09

Dear Bird Users, we (Vienna Internet Exchange) are one step closer to deploying bird into beta for our exchange - we have an automated configuration generation tool that grabs all data from our database and creates a bird.conf (ipv6 support is on it's way). Now the same tool that generates the configuration will also reload bird. As all this doesn't need human intervention it would be great to find out - before reloading bird - if the configuration file is syntactically correct (I realize that bird doesn't crash or anything if it can't read the config, but I need to know it anyway) - is there a way to find out if bird would accept the config-file - other than calling configure soft from birdc and parsing the output? Ideally I'd like to call 'bird -c /etc/bird.conf --check-config' and check the return-status of this script. I guess this wouldn't be hard to do, would it?

default bgp_med not working
by Wolfgang Hennerbichler 19 Nov '09

19 Nov '09

Hi Birdies, I've got a good reason to belive that the option 'default bgp_med' is not working (at all), at least in my setup. I do something like this in a filter: export filter { if from = 1.2.3.4 then { print bgp_med; print from; print net; bgp_med = bgp_med + 1; accept; } and I have output like that: 0 1.2.3.4 194.0.2.0/24 0 1.2.3.4 194.0.1.0/24 (void) 1.2.3.4 213.135.40.0/23 (void) 1.2.3.4 213.135.32.0/21 0 1.2.3.4 143.224.0.0/16 => those void's are disturbing, aren't they? Even adding the option default bg_med 10 doesn't change the bgp metric. So I guess I found a bug? I could only work around it by setting the bgp_med in the import filter.

RIP question
by David J Craigon 18 Nov '09

18 Nov '09

Hello, Me again, I'm afraid. What does "AUTH: MD5 protected packet with lower numbers" mean? I'm using RIP to talk to Quagga RIP. Sometimes it works, and sometimes I get this. David

log file getting too big
by David J Craigon 18 Nov '09

18 Nov '09

Hello, A bug report / feature request. I'm using the log "" command to log to a file. 1) The file seems to have a 2Gb limit on file size. 2) When the file gets to 2Gb, bird crashes. Can you make 1) use the large file things so it can be bigger than 2Gb, and can I suggest that 2) is not the right answer- the log file not being available seems like a really bad reason to bring down the entire network. Thanks, David

SNMP monitoring
by David J Craigon 17 Nov '09

17 Nov '09

Hello, a) I'm trying to monitor bird via SNMP so I can put it into Nagios. I want alerts to go off when a routing protocol session goes down, or if I am receiving not an defined number of routes. Any ideas? b) With the aim of achieving a) I am trying to write something automatic using birdc: Basically I'm trying run birdc from a program. The program will type commands into birdc, then act on the information. Here is my problem. You can recreate it by doing "birdc > file" and then examining file afterwards. Here's what I got: " BIRD 1.1.4 ready. bird> show protocols bird> ^M^[[Kname proto table state since info bgp_export Static master up Oct18 direct1 Direct master up Oct18 kernel1 Kernel master up Oct18 device1 Device master up Oct18 ebgp BGP master up Nov13 Established bogons Static master down Nov12 rip1 RIP master up Nov12 ibgp BGP master up Nov16 Established bird> exit " What's with the bird> ^M^[[K bit? I'm guessing it brings it back to the beginning of the line. Why does it do this? David

RIP / OSPF co-operation
by asaf＠lingnu.com 16 Nov '09

is it possible to share routing information retrieved by one protocol with other protcol ? say my router runs both RIP and OSPF, is it possible to broadcast information retrieved by RIP, through the OSPF protocol ?
